Abstract

Downhole tools and methods and systems associated therewith, wherein the downhole tools comprise a body and at least one sealing element comprising an aqueous-degradable thermoplastic rubber copolymer composed of a thermoplastic component and a rubber component. The thermoplastic component is present in an amount of about 5% to about 95% by weight of the aqueous-degradable thermoplastic rubber copolymer, and at least a portion of the sealing element hydrolytically degrades when exposed to an aqueous fluid.
